How do you know that I don't want to use my bandwidth quota to see
your site fully if I chose to navigate to it?

Why should you drain my batter faster if the battery is more full?
(For stuff like throttling down animation and XHR polling, the UA
should probably prevent background tabs from draining battery even
when the battery is near full regardless of whether the site/app is
benevolently cooperative.)
